Abstract: PURPOSE:To improve the tensile strength of a carbon fiber containing fine particles for improving the performance of the fiber or imparting additional function to the fiber. CONSTITUTION:The objective carbon fiber contains fine particles exclusively in the inner layer of single fiber. The fine particle-containing carbon fiber has high tensile strength and is hardly producible by conventional process. The fiber has high tensile strength as well as improved performance or imparted additional function by the mixing of fine particles. Since the carbon fiber has high tensile strength and excellent elastic modulus, compressive strength, electrical conductivity, electric wave shielding property or heat-resistance, it is useful as a reinforcing fiber for a composite material containing thermosetting resin, thermoplastic resin, ceramic, metal, etc., as a matrix, concretely, aircraft such as supersonic flying object, space articles such as rocket and truss, sports goods such as fishing rod and golf shaft, electric wave shielding material and heat- resistant member.

Abstract: PURPOSE:To enable the easy attachment/detachment of a cover and straightening plates and the fitting of the straightening plates at specific positions by providing a cover which is fixed to the straightening plates to cover a discharge pipe and the upper and side parts of the straightening plates. CONSTITUTION:The cover 52 and straightening plates 38 and 39 are fitted to a development part by inserting a positioning plate 162 into between positioning plates 166 and 168 while the straightening plates 38 and 39 are united with the cover 52 and mounting a cut 164 on both spray pipes 48 and 50. Consequently, the straightening plates 38 and 39 and cover 52 are arranged at specific positions about the spray pipes 48 and 50. When the cover 52 and straightening plates 38 and 39 are detached from a developing tank main body in this state, the cover 52 is lifted and the positioning plate 162 is extracted from between the positioning pins 166 and 168. The straightening plates 38 and 39 are also lifted together and detached from the developing tank main body. Consequently, the positioning and fitting of the straightening plates 38 and 39 and cover 52 are facilitated.

Title: Water ink for ball point pen
Inventor: HAMAMOTO HIDETOSHI
IPC: C09D11/16
Filed: 1980-03-18
Abstract: PURPOSE: To provide water ink for ball point pens, by which wear of a chip due to friction between the chip and a ball is prevented, containing a water-soluble dye, a water-soluble org. solvent, water and an unsaturated fatty acid.  
     CONSTITUTION: There is provided an ink containing a water-soluble dye, a water- soluble org. solvent, water and an unsaturated fatty acid. It is presumed that said unsaturated fatty acid produces a pasty compd. on the surface of a ball to form a film on the surface of the ball. As a result, friction coefficient is lowered, lubricity becomes good and the rotation of the ball is made smooth, and thus the wear of a chip is prevented. It is also presumed that when a satd. fatty acid is used, a powdery compd. is produced on the surface of the ball and hence a film is not formed on the surface of the ball. Thus, the satd. fatty acid has no effect on lubricity. Said water-soluble org. solvent has compatibility with water and is used as an auxiliary.

IPC: H01F10/12
Filed: 1995-02-23
Abstract: PURPOSE: To manufacture a thin film noise filter which is not much changed in permeability by an external magnetic field such as geomagnetism, capable of being mounted in a multilayered circuit board, and large in impedance characteristics. CONSTITUTION: A thin film noise filter is formed of soft magnetic thin film, wherein a composite magnetic anisotropic multilayered film which is isotropic and high in permeability in all directions on its surface is used as the soft magnetic thin film. For instance, composite magnetic anisotropic films 2 and 3 are provided sandwiching a spiral coil 1 between them through the intermediary of an insulating layer, wherein each of the films 2 and 3 is of multilayered structure composed of eight layers which are each composed of an amorphous metal magnetic layer and an insulating layer and changed from each other in anisotropic direction by an angle of 45 deg.. The thin film noise filter of this constitution is hardly affected by a bias magnetic field, so that it has such a merit that it is not affected by a change in an ambient magnetic field.

Title: Tuner device of television receiver
Inventor: FUJIMOTO ISAO
IPC: H03J3/18
Filed: 1980-03-19
Abstract: PURPOSE:To cause the tuning range to meet standard requirements (DOC and so on), by raising the upper limit value of the tuning voltage only at the VHF high band receiving time. CONSTITUTION:Three tuning circuits are provided for the VHF low band, the VHF high band, and the UHF band, and tuning circuits and tuning voltages are switched while interlocking with the band change-over switch. Since upper and  lower limit values of the receivable range in the VHF high band are regulated in  DOC standards of Canada, half-fixed resistor 53 is controlled under the state, where variable resistor 51 is turned up to the upper limit, to regulate the tuning voltage, and thus, only the upper limit of the receivable range in the VHF high band is regulated effectively without influencing receiving of other bands at all. Variable resistor 54 is controlled to regulate the lower limit in the VHF high band.

When the (b) mode is selected, something to be expressed in the character as editing information (input coordinate value, for example) generates the character in a suitable position and the something to be expressed in the graphic or symbol (a polygon to show a designating area in a figure or a +character part, etc., to show a coordinate position, for example) generates the graphic and symbol in the suitable position. Thus, they can be confirmed on a copy with being synthesized with the real picture. Thus, when there is an error in a coordinate system to be used for the edition, the error can be corrected in advance the efficiency of editing operation can be improved.

Title: Formation method of interconnection
Inventor: YAMAHA TAKAHISA
IPC: H01L21/3205
Filed: 1990-02-16
Abstract: PURPOSE:To arrange that excess silicon in a silicide layer is absorbed by a metal layer and to prevent the excess silicon from being precipitated as a lump in an Al-alloy layer on the silicide layer by a method wherein, after the metal layer has been formed under the silicide layer, a silicification treatment is executed. CONSTITUTION:Silicon in a silicide layer 16 react with a titanium layer 15 to transform the titanium layer 15 into a titanium silicide layer 15A. At this time, the titanium layer 15 acts to suck excess silicon in the silide layer 16. Then, the laminate of the titanium silicide layer 15A, the silicide layer 16 and an Al or Al-alloy layer 18 is patterned according to a desired interconnection pattern to form a first interconnection layer W1. A contact hole 20a corresponding to one part of the first interconnection layer W1 is made in an insulating film 20. After that, an interconnection metal is applied to the surface of a substrate; it is patterned to form a second interconnection layer W2. Thereby, it is not recognized that a silicon lump is precipitated; the first interconnection layer W1 can keep a low-resistance electrical connection state with reference to both a region 12 and the second interconnection layer W2.
